Can you attach the dmesg or /var/log/messages from this machine as a text/plain attachment? Stanislaw is going to want to see the backtrace and I'm curious why you have the F taint flag set on this oops. It probably shouldn't be.

So I finally think I got a clue...
Does this happen when you have a lot of traffic?
I can see that you have an eeePC. I guess it runs Atom.
What I am guess here, is that the Rx handler isn't fast enough to handle the Rx buffers, and the HW complains that there are no descriptors left.
This is what
Nov 5 20:40:55 localhost kernel: [ 764.973959] iwlwifi 0000:01:00.0: 0x0000000C | FH_ERROR
hints. I am quoting the logs so that you will know how do decide if another issue is the same bug or not.
I am still not sure about all this and will probably need more data, therefore I am asking again: is it easily reproducible?

Mikhail, please *always* provide logs when you report.
When you are saying that you are "having this issue" it is not precise enough.
*that issue* doesn't tell me anything. At least tell me you saw the FH_ERROR line so that I can be sure. But in that case I will ask you the whole log since we print registers that can hold valuable data.
Also I really don't understand how "switch off internal WiFi/WiMAX card" can be related to the scenario I described (the driver not being fast enough to feed the HW with fresh Rx buffers).
I am really trying to help but can't really unless you provide good inputs which means:
a scenario and a log. always. Also please consider that 2 logs look alike and then no need to send them. If the logs are really the same, I will make the decision that one of them is redundant by myself.
Thanks
